Both products were isolated as air-stable microcrystalline solids and were fully characterized by IR spectroscopy, elemental and thermogravimetric analysis, and powder and single-crystal X-ray diffraction. Structural and topological features of CP 1 and MOF 2 were analyzed in detail, allowing to identify a topologically unique 4,5,5,6-connected net in 1 or a very rare 4,4-connected net with the isx topology in 2. Thermal stability and solid-state luminescent behavior of 1 and 2 were also investigated. Apart from revealing a notable topological novelty, both compounds also represent the first structurally characterized Pb(II) and Zn(II) derivatives assembled from H3cpta, thus opening up the application of this unexplored pyridine-tricarboxylate block in the design of new metal-organic architectures.<\/jats:p>","DOI":"10.3390\/cryst8090353","type":"journal-article","created":{"date-parts":[[2018,9,3]],"date-time":"2018-09-03T10:50:51Z","timestamp":1535971851000},"page":"353","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["New Topologically Unique Metal-Organic Architectures Driven by a Pyridine-Tricarboxylate Building Block"],"prefix":"10.3390","volume":"8","author":[{"given":"Jinzhong","family":"Gu","sequence":"first","affiliation":[{"name":"College of Chemistry and Chemical Engineering, Lanzhou University, Lanzhou 730000, China"}]},{"given":"Yan","family":"Cai","sequence":"additional","affiliation":[{"name":"College of Chemistry and Chemical Engineering, Lanzhou University, Lanzhou 730000, China"}]},{"given":"Min","family":"Wen","sequence":"additional","affiliation":[{"name":"College of Chemistry and Chemical Engineering, Lanzhou University, Lanzhou 730000, China"}]},{"given":"Zhijun","family":"Ge","sequence":"additional","affiliation":[{"name":"The Yixing Medical Center of Jiangsu University, Yixing 214200, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2052-5280","authenticated-orcid":false,"given":"Alexander M.","family":"Kirillov","sequence":"additional","affiliation":[{"name":"Centro de Qu\u00edmica Estrutural, Instituto Superior T\u00e9cnico, Universidade de Lisboa, Av.
